Option Menu example in android studio| How to set option Menu in Actionbar

Option Menu:-Android Option Menus are the primary menus of android. They can be used for settings, search, delete item etc.
Here, we are inflating the menu by calling the inflate() method of MenuInflater class. To perform event handling on menu items, you need to override onOptionsItemSelected() method of Activity class.
We are going to see  example of option menus. We will see the simple option menus and second, options menus with images.

Required Classes and xml layouts:-
1.MainActivity.java | activity_main.xml
2.Home.java | home.xml
3.menu (create directory inside res with the name menu) | option_menu.xml(right click on menu->new->Menu resource file->give name option_menu.xml->ok. )

PopUp Menu Example in Android Studio

1. Android PopUp Menu?

Example of PopUp Menu:
Required class,file,&layouts:-
1.MainActivity.java | activity_main.xml
2.Login.java | login.xml
3.Make Folderinside res:- menu | popup_menu.xml
Step1:-Take new project and add new folder inside res.Right Click on  res->new->Directory->set name menu->ok.Now right click on menu folder and add new layouts for popup menu options. res-.menu->right click on menu->new->Menu resource file->give name popup_menu.xml->ok.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
        <item

View Pager Example in Android Studio

1. What is ViewPager?
Ans:-Layout manager that allows the user to flip left and right through pages of data. You supply an implementation of a PagerAdapter to generate the pages that the view shows. ViewPager is most often used in conjunction with Fragment , which is a convenient way to supply and manage the lifecycle of each page.

Here we will see how to implement ViewPager in Android Application.For this Example we will create 3 Layouts and their JAVA class and add these Layouts to MainActivity.java.Following are the site map.
1.MainActiviry.java  | activity_main.xml
2.ViewPager1.java  | view_pager1.xml
3.ViewPager2.java  | view_pager2.xml
4.ViewPager3.java  | view_pager3.xml

Step 1:- main_activity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="supriya.com.viewpagerexample.MainActivity">

    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/vPager">
</android.support.v4.view.ViewPager>
</RelativeLayout>

Step 2:- MainActivity.java

package supriya.com.viewpagerexample;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
    ViewPager vpager;

    @Override    

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        vpager=(ViewPager)findViewById(R.id.vPager);
        vpager.setAdapter(new setViewadapter(getSupportFragmentManager()));
    }
    public class setViewadapter extends FragmentPagerAdapter {
        public setViewadapter(FragmentManager fm) {
            super(fm);
        }
        @Override        

public Fragment getItem(int position) {
            if(position==0) {
                return new ViewPage1();
            }
            else if (position==1){
                return  new ViewPage2();
            }
            else                

                 return new ViewPage3();
        }

        @Override        

public int getCount() {
            return 3;
        }
    }
}

Step 3:- view_page1.xml
<?xml version="1.0" encoding="utf-8"?>

@Nullable Bundle savedInstanceState) {
        View v=inflater.inflate(R.layout.view_page1,null);
        return v;
    }

Step 5:- view_page2.xml

        android:text="ViewPage2"
        android:textSize="25sp"
        android:textAlignment="center"
        android:textColor="#ffffff"/>

</LinearLayout>
Step 6:- ViewPage2.java

        View v=inflater.inflate(R.layout.view_page2,null);
        return v;
    }
}

Step 7:- view_page3.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
